Specification of Letters Patent.

Patented July 7, 1908.

Application filed March 14, 1907. Serial No. 362,284.

I To all whom it may concern:

Be it known that I, JOSEPH W. LACROSS, a citizen of the United States, residin at the city of Providence, in the county 0 Providence and State of Rhode Island, have invented certain new and useful Im rovements in Machines for Covering Boardinders, of which the following is a specification, reference being had therein to the accompanying drawing. v

This invention relates to machines for covering the edges of board winders, reels or the like, and has for-its object to provide a machine which will automatically apply a ribbon of pa er, fabric, or other suitable ma terial, to t e edges of a board or reel on which yarn, Webbing, cloth, or the like is wound.

In practice when the cloth or webbing is wound onto the board it usually leaves the ends or edges of ,the same exposed, and it has been the custom to cover these edges with a tinted aper or fabric to give the package a more nished appearance. Most of these boards have heretofore been covered by hand-labor, which was necessarily very slow and expensive, at the same time the work was not accurate or uniform, but by the use i of my machine these boards may be covered very rapidly and with absolute uniformity, at

the same time reducing the expense of covering to a minimum.

The invention is fully set forth in this specification and more particularly pointed out in the appended claims.

In the accompanying drawings: Figure 1 is a lan view of the machine. Fig. 2 is an en arged detail of one of the winding boards covered on its edges. Fig. 3is a sectional view showing the magazine in which a large number of the boards are stored, also showing a portion of the carrier belt. Fig. 4is an enlarged detail of a portion of the chain belt showing one of the carrier plates attached thereto. Fig. 5-is a side elevation of a portion of the machine, showing the roll from which the ribbon is fed to the machine, said roll being supported on the side of the magazine, also showing the manner of-carrying the ribbon over the roll to moisten or apply cement to the face of the same before it is attached to the boards. Fig. 6is a section on line 6-6 of Fig. 5 showing the guides 28' for the boards as they are carried from the magazine to the'folding fingers. Fig. 7is an end view of the folding fingers showing the manner in which they are flexibly supported to exert a tension on the edge of the boards as. the cover is led therethrough. Fig. 8is a perspective view re resenting a pair of folding fingers and a ri bon being fed through each of said fingers and being applied to the edges of a board, said board being in the act of passing through one air of the rolls which press the covering firm y onto the same. Fig. 9is a front elevation showing a pair of the rolls with the center portion of each cut away to allow the chain and carrier plate to pass therethrough. Fig. 10is an end view showing the roll bearing frame-and the tension spring which causes said rolls to press the covering tightly onto the edges of the board. Fig. 11is a side elevation showing the cutters which sever the ribbon after having been applied to the board. Fig. 12-is an end elevation of both pair of rolls showing the position of the cutters between the same, also showing the carrier belt which receives the finished boards and deposits them in a proper receptacle in the end of the machine. Fig. 13is a detail of the blade supporting collar. Fig. 14is a detail .of a cutter blade.

Referring to the drawings, at 1 is the frame of the machine which may be made in any convenient form, but is preferably made in the'form of a table on the upper face of which the operating mechanism is mounted, the primary driving pulleys, shafts and gears being arranged on the framework below the top of the table for convenience.

At 2 is the sprocket wheel through which the carrier belt is driven. This sprocket is mounted on its driving shaft 3, which extends out over the edge of the table and receives its motion from the main driving pulleys 4 through the shaft 5, gears 6, 7, 8 and 9, shaft 10, gears 11 and 12, through the inclined shaft 13, and gears 14 and15. The outer end of this sprocket driving shaft is also provided with a hand-wheel 1.6 by which the mechanism may be moved and fed by hand when desired.

The driving sprocket wheel .2 imparts a uniform motion to the carrier belt 17, which belt is led along over the top of the machine, back beneath the table 18 and around the s rocket 19 at the entering end of the same.

his carrier chain is provided at intervals with small plates or fingers 20, each of which are permanently; secured;to;a link in the engage one of the boarcls 26, as it chain. These fingers extend outward from; theface of the chain belt and. are adapted to asses through the magazine and carry said oard through the machine to be operated upon These plates in ractice are usually set in the belt about the ength of a board apart.

' The sprocket wheel 19 is.r nounted on the shaft 21, which shaft in turnis mounted on the sli plate 22 that is held to be adjusted endwise y'the screw 23 thereby providing convenient means whereby the tension of this carrier chain belt may be nicely regulated by moving the hand-wheel 24.

At 25 is a magazine which is made in the form of a tall receptacle formed of a shape and size to receive a large number of winding boards 26 piled one upon the other. At the lower edge of this ma azine is a narrow slot or o ening 27 just wide enough to admit of one oard assing therethrough at a time.

One of the essential features of my device is the construction of the ribbon folding fingers 2828. These fingers are preferably made of thin metal and are formed slightly concaved at the entering end 29, the edges be' turned over forming inwardly extending l i ps or flanges 30.30 through which the ribbon is guided and started on its folding action. From theentering end these fingers are turned gradually inward and drawn together to bring the edges of-the ribbon tor wards each other until at their opposite ends they form a narrow slot '31 just wide enou hto receive the edge of the board 32 and t e ribbon ofTplaper' turned or folded over it, see

Fig; 8.

ese fingers are preferabl mounted on the two arms 32-32' e at their lower ends 33 said arms be' he d in an upright position against thestop block 34 by means of the tension springs 35-35, see Fig.

pressing rolls both rolls in each set being ters are constructed with cutter blades 43 43, each blade being fastened by means of the. screw 44 to the lip 45 of the col1ar46. The blades are set on a slight angle so that when'the upper and the lower blades come together they cut with a shearing action readily severing the covering of paper or cloth-between-the ends of the boards upon each revolution of the shafts, These shafts are geared together at their outer ends by ears 4747, the lower shaft being driven om the sprocket driving shaft 3 through the sprocket 48, small sprocket 49 and boards are rocketchain 50to run at a speed to cause s t e cutters to sever the ribbons at the end of each board. At 5l'-51 are (guide plates over which the asse after leaving the rolls 37. They are' t en transferred to the carri 'ng belt'52 which removes-them to the end 0 the table. This carrier belt runs on the pulleys 53 at its upper end and 54 at its lower end,

which latter pulley being mounted on the shaft 55 is driven from the shaft 56 through the pulleys 57 and 58 and belt 59.

The ribbons of material, which are applied to each side of the boards, are preferably brought to the machine on rolls"6060 WhlCh rolls are supported to turn freely on pins 6161 on either side of the magazine casing. Each ribbon 62 is led from its individual roll down under the guide roll63, up under the contact or pressure roll 64,-.and over the top of the moistening roll 65, thence through the guidewire 66, supported on the post 67, there it is turned up on its edge and carried through the, folding fingers 28 -28, where the edges are bent or folded over the edge of the boards as they move along therewith. The springs 35 on-said fingers tend to press the material tightly to the edge of the' card and the rolls 36 and 37-press'the same tightly to the top and bottom of the boards and cause it to adhere firmly thereto. The movement of the boards to which the rib-' bons are attached, serve to draw them inat a corres onding speed to be subsequently attache to the boards which follow. After these ribbons have been firmly attached to both edges of the boards by passing throu h thefirst set ofrolls they are severed by t e cutters and then carried out through the second set of rolls.

. At 68 is a trough which may contain either cement or water, the same being replenished from the reservoir 69 through the supply pipe.70. In practice when t e ribbons are gummed and dried before be' brought to the machine, water is held lll lile trough 68 and is carried by the soft-faced roll 65 to moisten the gummed face of the same, but when the ribbon has not been previously gummed the trough 68 contains cement which is applied to one face of said ribbon as it asses over the roll.

his machine is comparatively sim Is in construction and may be run without t e aid of a skilled attendant, it being only necessary to keep the magazine supplied with boards and the troughs with the cementing material, and after first threading up the ribbons and getting the machine started it will continue to run and automatically cover the boards in an accurate and uniform manner.

at a very rapid rate, severing the ribbons and depositing the finished boards at the opposite end of the machine.
